问题分析和解决

回答1:

OK, just found out, as per github.com/protocolbuf…

The v1.20 protoc-gen-go does not support generating gRPC service definitions. In the future, gRPC service generation will be supported by a new protoc-gen-go-grpc plugin provided by the Go gRPC project.

The github.com/golang/protobuf version of protoc-gen-go continues to support gRPC and will continue to do so for the foreseeable future.

EDIT 29/05/2020:

Following an update from @Mark in the comments, according to the Tracking issue on github, protoc-gen-go-grpc has now been merged. However, according to the same issue:

Even with this merged, it is unreleased (v0.0) and subject to change. We do plan to add a requirement that the Unimplemented service implementation be included in all registered services, with an escape hatch in the form of a command-line arg as suggested by @neild.

If you haven't done, so you need to install the protoc-gen-go plugin like so:

go get github.com/golang/protobuf/protoc-gen-go
复制代码

this will install the plugin (if your GOPATH is ${HOME}/go) to:

${HOME}/go/bin/protoc-gen-go
复制代码

Then when running protoc, either update your path, or set it dynamically like so:

PATH="${PATH}:${HOME}/go/bin" protoc ...
复制代码

回答3:

the missing plugin has been implemented at github.com/grpc/grpc-g….

command below should fix it

go install google.golang.org/grpc/cmd/protoc-gen-go-grpc
复制代码
